Abstract
Resonant passive mode-locking (RPM) is a new coupled-cavity mode-locking technique where a resonant nonlinear reflector (i.e., quantum well reflector) in a coupled cavity of a cw laser strongly induces mode-locking (Fig. 1). Using a GaAs/AlGaAs multiple-quantum-well (MQW) reflector, a RPM Ti:Sapphire laser produces tunable picosecond pulses1 without dispersion compensation inside the main cavity. Using a strained layer InGaAs/GaAs MQW reflector, an RPM Nd:YLF laser at the wavelength of 1.047 μm produced 4 ps pulses (Fig. 2) with 1.6 nJ pulse energy at a 250 MHz repetition rate (390 mW average power) with 1.5 W pump power from a Ti:Sapphire laser.2
